SPECIFICATION forming part of Letters Patent No. 412,644, dated October 8, 1889.

Application filed February 19, 1889- Serial No. 300,408. (No model.)

To aZZ whom it may concern: I

Be it known that I,HERMANN.,H. B.MEYER, of Brooklyn, county of Kings,'State of New York, a citizen of the United States, have invented an Improved Indicator-Valve, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an indicator device for automatically showing the position of a valve in its chamber; and my invention consists in the combination, with the stem of the valve, of two disks located one above the other flatwise, the upper disk being adapted in diameter or area to cover and conceal the under disk, and the said disks being adapted to slide or moveone over the other in the direction transversely of each other, and actuating mechanism, substantially as hereinafter set forth, intermediate said valvestem and the disks, whereby the movement of the stem in opening and closing the valve will give a concurrent and corresponding movement of the disks over each other flatwise transversely, so that it may be readily perceivedwhat position the valve has relatively to its seat by noting to what extent the upper disk covers the under, as hereinafter specified.

Figure 1 is aside elevation of a globe-valve with an indicator containing my invention. Fig. 2 is avertical section of the parts shown in the upper portion of Fig. 1, and taken on line as m, Fig. 3; and Fig. 3 is a plan of the parts shown in the upper portion of Fig. 1.

A is a globe-valve, and B is the valve-stem thereof.

0 represents a flooring or platfornnbelow which the valve is shown' and through and above which the stem B extends. I

D is a standard or frame fixed on the dooring and constituting a bearing in which the valve-stem works.

B is a hand-wheel on the valve-stem, by means of which the same is operated.

This character of valve and the described location and arrangement of its operative parts are employed in places (notably in gas-works) where the pipes controlled by the valve are below a flooring or under ground and the actuating parts are manipulated above said flooring. Where the valve is thus separated from and not visible at the place of manipulation of its actuating parts, my present invention is designed for use in indicating to the person manipulating the hand-wheel B the position of the valve in its chamber as the valve is opened or closed.

E and E are two disks, which are prefer 6o ably circular, and both of the same or equal area or diameter, so that one will cover and conceal the other when placed one above the other coincidently fiatwise. I arrange these .disks so that they willslide over or past each other transversely of each other fiatwise, and to accomplish this I find it preferable to fix or mount one of the disks, desirably the under one, rigidly upon a frame or standard e, as

shown at E. The other or upper disk E, I

mount upon a platform 2, which is desirably a part of said frame 6, and may be extension laterally from the disk E. The frame e, disk E, and platform c may be cast or formed in one piece, as slrown in the drawings. The 7 disk E, resting and riding on the platform e, is capable of moving over and upon and covering the disk E, and of moving transversely flatwise away from and off of and uncovering partially or entirely the said disk E. l

I communicate the motion of the valve-stem B in opening or closing the valve in its chamber to the disk E in the above-described preferable arrangement by suitable mechanism connected to and actuating said disk E and a intermediate said disk and valve-stem, ar-

ranging and locating the parts relatively to each other, so that when the valve is closed the disk E is over and covers the disk E, and

so that as the stem B moves to open or thereafter to close the valve the disk E will be given a concurrent movement flatwise in the direction transversely to and away from and off of the disk E, or in the direction toward and over said disk. I show an acuating mechanism in the drawings which accomplishes" this purpose. The disk E is carried by or connected to a nut 6 and the platform e may be longitudinally slotted, as shown at 6 to I permit the play of the nut, and said nut works upon and traverses a screw 6 journaled in valve-stem and operated by said stem,wherethe frame 6. The said frame being mounted by said disks are caused to move fiatwise 5 upon. the top or upper end of the standard I), transversely one upon the other concurrently which I find preferable, and desirably extendwith the movement of the valve-stem in opening at right angles thereto below the handing and closing the valve, substantially as wheel B, so that the disks E and E are in a and for the purpose specified.
